FMSCA Regulation 350.335
350.335 What are the consequences if my State has laws or regulations incompatible with the Federal regulations?
(a) A State that currently has compatible CMV safety laws and regulations pertaining to interstate commerce (i.e., rules identical to the FMCSRs and HMRs) and intrastate commerce (i.e., rules identical to or within the tolerance guidelines for the FMCSRs and identical to the HMRs) but enacts a law or regulation which results in an incompatible rule will not be eligible for Basic Program Funds nor Incentive Funds.
(b) A State that fails to adopt any new regulation or amendment to the FMCSRs or HMRs within three years of its effective date will be deemed to have incompatible regulations and will not be eligible for Basic Program nor Incentive Funds.
(c) Those States with incompatible laws or regulations pertaining to intrastate commerce and receiving 50 percent of their basic formula allocation on April 20, 2000 will continue at that level of funding until those incompatibilities are removed, provided no further incompatibilities are created.
(d) Upon a finding by the FMCSA, based upon its own initiative or upon a petition of any person, including any State, that your State law, regulation or enforcement practice pertaining to CMV safety, in either interstate or intrastate commerce, is incompatible with the FMCSRs or HMRs, the FMCSA may initiate a proceeding under 350.215 for withdrawal of eligibility for all Basic Program and Incentive Funds.
(e) Any decision regarding the compatibility of your State law or regulation with the HMRs that requires an interpretation will be referred to the Research and Special Programs Administration of the DOT for such interpretation before proceeding under 350.215.
